IPADLOCK.

Application filed. May 3, 1923 Serial No. 636,399.

The object of our invention is to design a padlock so-that it can be secured to a grooved pin, or bolt, made in one or two parts so that, while the lock will turn freely on the pin, it cannot be removed therefrom without a key.

The present invention is especially adapted for securing spare wheels to the carrier of an auto-mobile. These spare wheels are usually secured tothe carrier by two or more pins. One of the pins is generally provided with a transverse hole to receive the shackle of an ordinary padlock.

It will be understood that the invention can be used for other purposes without departing from the essential features of the invention.

In the accon'ipanying drawings:

Fig. 1 is a face View of the lock, showing it mounted on a grooved pin;

Fig. 2 is sectional View on the line 22, F 1;

F 3 is a face view, partly in section, showing the lock engaging the grooved portion of the pin;

Fig. is a detached perspective view of the lock, showing the shackle raised;

Fig. is a perspective viewof one form of pin to which our improved lock can be applied 1;

' Figs. 6 and 7 are views illustratinga modification of the invention, in which the pin has a flat side; a

8 and 9 are views illustrating another modification, in which the side plates of the casing are shaped to enter a groove on each side of the groove in which the sl'lackle is located;

Fig. 10 is a side view, partly in section, shov-Jing a rib at one side of the shackle;

Fig. 11 is a face view of a lock having a sliding shackle arranged'to engage a pin; Fig. 12 is a 'view showing a modification of the pin;

Fig. 13 is a view showing the invention applied to a door;

Figs. 14 and 15 are views illustrating the invention applied to a two-part pin; and

Fig. 16 is a view illustrating the pin made of pressed sheet metal.

' Referring to Figs. 1 to 5 of the drawings, 1 is apin having a reducedportion in the form of an annular groove 2. In the present wheel frame of an automobile and passes through the hub 3 of the spare wheel. 4 is the lock casing and 5 is the shackle pivoted at 6 to the casing. The casing has a body portion 8, a cap plate 9, and a back plate 10, which is shaped similarly to the cap plate. The cap plate and the back plate have portions 11, that are shaped to conform to the heel portion of the shackle 5, Fig. 1, and extend on each side of the shackle, as shown. The, shackle 5 enters an opening 12 in the casing and is engaged by the 'ordinary locking mechanism, not shown. Extending from the casing between the two portions oft-he shackle is a rib 13, which is shaped as shown in Figs. 2 and 3, so as to fit a portion of the groove 2 in the pin 1 when the shackle is inthe closed position. The shackle is shaped to-fit the other portion of the groove, as clearly shown in Figs. 2 and 3, so that, when the shackle is in the locked position, the lock casing is held onto the pin, preventing the withdrawal of the spare wheel from the pin, but the lock casing can turn freely on the pin so that it is diflicult to hold the lock in the endeavor to free the shackle without a key. Two or vmore grooves are preferably formed in the pin to accommodate wheels having different thicknesses of hub, although, where a pin is made for a special type of wheel, one groove is suiiicient.

In Figs. 6 and '2', a modification is shown in which one side of the pin 1 is fiat to fit of the casing 4? of the .rib 13 adapted to a groove 2 at the side of the main groove. This lock can only be placed in position with the face outwards so that, when the key hole is in the face, it is always accessible.

Fig. 11 is a view showing the invention applied to a lock having a sliding shackle 5 The rib 13 projects into the groove of the pinl between the arms of the shackle.

Fig. 12 shows a pin 1 having a head and a grooved portion of the .pin extends. The

lock 4 is secured to the projecting portion of the pin, holding the door closed.

I In Figs. 14: and 15, a two-part pin is illustrated,,which is particularly adapted to secure sliding doors in position. The two parts 1 are each secured to'a sliding door 1.8. WVhenithe doors ,are closed, as in Figs. 14 and 15, the itwo parts form a complete pin with anannnlar groove therein to receive the padlock. v 7

- ,InEig. 16, a pin isjshowninadc of struck up sheet metal. It will be understood that the groove, or reduced portion of the pin, may be of any shape desired to correspond with the shape of the shackle and the rib on the lock easing.

WVe claim:

- :1. The combination in a padlock, of a ca in-g "having a body portion, a cap plate and back plate; and a shackle'adapted tothe casing, said casing having a rib projecting into thQ SPHCB bQtWGQIL-thB aIIDS'Of theshackle, the

cap plate and back plate having portions extending on each side of the shackle at one side of the casin and conforming to the portion having a backplate and a cap plate, each 01" said plates havlng anextension at the pivot end of theshackle and conforming to the shape of the shackle, the lock casing having a rib extending into the space between the; arms of the shackle, the rib and the shackle be ingarranged to enter a groove in a projecting pin. 7 f

8. The combination of a two part pin, each part having a groove therein, thegrooves being inialignment one with the other; a lock casing having a rib, and a shackle on the lock casing, the shackleand rib arranged to enter the groove in the two part pin.-

4. The combination in a padlock of a Case ing consisting of a body portion and cap and back plates, a shackle the same Width as the body portion; the body portion having a I rib of the same Width as the shackle and ex tending beyond the front and back plates and between the arms of the shackle and arranged to engage a pin projecting through the space between the shackle and rib.
